On a 1.67" OD Schedule 40 pipe handrail (1.5" nominal pipe), this knurled cap closes the run with a cross-hatch textured face: a press-fit plug that seats inside the pipe end and sits flush at the end of a waterfront rail, pier run, or exterior pipe railing. Offered in 316 polished or satin stainless for .080" Schedule 40 wall pipe, it holds up to salt air, chlorine, and weather. Choose polished for a bright finish or satin for a softer, low-glare look. Purely cosmetic — it caps the pipe end with a textured face, no structural role — and matches the rest of a 316 pipe-handrail run.
